IMPROVEMENT IN ROLLER RAZOR-SHARPENER.

Specification forming part of Letters Patent No. 191,859, dated June 12,1877 application filed May 5, 1877.

To all whom it may concern Be it known that we, WELMER T. JAHNE andCHARLES H. WHITE, of Jersey City, in the county of Hudson and State ofNew Jersey, have invented a new and useful Improvement .in Roller RazorSharpener, of which the following is a'specification:

Figure 1 is a top view of our improved machine, part being broken awayto show the construction. Fig. 2 is a vertical longitudinal section ofmy improved device, taken through the'line m m, Fig. 1. Fig. 3 is avertical crosssection of the same, taken through the line y y, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved device forsharpening razors, which shall be simple in construction, convenient inuse, and effective in operation, sharpening the razor quickly andevenly.

'The invention will first be described in connection with the drawing,andthen pointed out in the claims.

Aare two wooden rollers, which are covered with leather, and haveemery-flour applied to them. The rollers A are placed side by side, andtheir journals revolve in holes in metal plates B, which are connectedtogether by rods 0. The holes for the journals of one or both therollers A are elongated horizontally, so that they may move apart toreceive a thicker blade.

The rollers A are held together to bear against the sides of the bladeby Usprings l), which pass around the rods 0, and the ends of which areconnected with the journals of the said rollers.

To the journals of the rollers A are attached gear-wheels E, the teethof which mesh into each other, so that the said rollers may revolvetogether and in opposite directions to grind both sides of the bladeequally.

The journals of one of the rollers A projcct, and to its end is attachedthe crank F, by which the machine is operated.

The parts thus far described are placed in a. wooden box, G, where theyare secured in place by screws H, passing in through the ends ofthe-said box G, and screwing into the plates B, the journal to which thecrank F is attached entering a notch in the end of the said box G.

The box G is provided with a cover, I, which is hinged to one side ofthe box G, and and is secured to the other side, when closed, by a hookand staple.

The cover I has a wide longitudinal slot formed in it, is recessed alongthe sides of said slot, and has the edges of two curved plates, J,pivoted to it along the shoulders of said recesses. The inner edge ofthe plates J projects through the slot in the cover I into the spacebetween the upper parts of the two rollers A, to guide and center theblade while being ground. The plates J are covered with leather toprevent the blade from being dulled byaccidental contact with saidplates.

The inner edges of'the plates J are adjusted according to the thicknessofthe blade by two long set-screws, K, which pass in through the coverI, and their forward ends rest against the inner sides of the plates J,as shown in Fig. 3, and in dotted lines in Fig. 1.

1n the end of the bottom of the box G is formed, or to it is attached, asocket, L, to receive the end of the short arm of the U-spring M, thelong arm of which is designed to pass beneath the table upon which themachine is placed, to hold the said machine steady while being used.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. The combination of the rollers A, coveredwith leather and coated with emery-flour, the plates B, the rods 0, thesprings D, the gear-wheels E, and the crank F, with each other,substantially as herein shown and de scribed.

2. The combination, with box G, of the herein shown and described.

4'. The combination of the set-screws K with the slotted cover I and thecurved plates J, substantially as herein shown and described.
